Alan Hudson, in Comprehensive Clinical Psychology, 1998. By choosing to catch the ball, they would not be able to hit a person at the same time. Click here to read an example of how a teacher used DRI … For most single case studies, the easiest reversal is to withdraw any intervention to see if the desired skill or behavior stays at the same level of performance. For example, if the plan is for the youngster to avoid picking at his face with his fingernails, we may reinforce him for "keeping hands in pockets" when he is socializing with others, but promote "hands away from face" during academic tasks. DRA, or Differential Reinforcement of Alternative Behavior, is an ABA technique used to reduce problem behaviors. DRA reinforces a specific behavior and only that specific behavior. Clapping hands may very well stop a child from hitting him or herself in the head in the short run, but in the long run, if hitting him or herself functions to provide an escape from non-preferred activities, clapping hands will only temporarily keep the child from hitting him or herself. (1990) found that DRI was most effective when the incompatible behavior was functionally related to the target behavior. In other words we don’t just seek to make a problem behavior stop. DRI: Differential Reinforcement of Incompatible Behavior. An effective way to get rid of a target behavior that may be causing difficulty for your student, preventing him or her from succeeding in gaining the skills they need is to find a replacement behavior and reinforce it. It is most powerful if that alternative behavior serves the same function for your student. This time the alternative behaviour is one that is incompatible with the unwanted behaviour – they cannot occur at the same time. In order to effectively extinguish a behavior, you need to be sure the replacement behavior serves the same function. Sitting in his seat is chosen as the incompatible behavior because it cannot occur at the same time as out of seat behavior. DRI (Differential Reinforcement of Incompatible Behavior) Reinforcing any behavior that would preclude the ability to engage in the targeted behavior. About the Author. Differential reinforcement of incompatible behavior (DRI) is a weakening procedure that is based on reinforcement. DRA: Mr. Martin decided it was time to address Jonathon's hand flapping. Example: Kevin engages in out of seat behavior so his teacher decides to implement a DRI procedure. Wood!". For any other response, the student does not receive reinforcement. For example, teachers working with children on the autism spectrum will often use DRO and DRA (Differential Reinforcement of an Alternative behavior) to shape behavior. She decides to reinforce a behavior that is incompatible with out of seat behavior. The difference btween dra and dri is that dri reinforces a behavior that is incompatible to the problem behavior and puts the target problem behavior on extinction. Let's Learn ABA Post navigation. An evaluation of existing research conducted by Carr et al. They have put scrunchy bracelets on her wrists and given her a lot of praise: i.e. He decided that Jonathon's hand flapping appears when he is anxious, and when he is excited. With our DRA example above, a student can sit at their desk with their hand up and still call out. When conducting single case research, the norm for studying the effectiveness of interventions with children with severe disabilities, a reversal is critical to providing evidence that the intervention really does create the effect you have seen in the intervention period. Using differential reinforcement of an incompatible behavior (DRI) may be an effective way to redirect a dangerous behavior, or it can be used as part of a behavioral (ABA) program that will extinguish the behavior. "What pretty bracelets you have, Emily!" Differential Reinforcement of Incompatible behavior (DRI), Differential Reinforcement of Alternative behavior (DRA), Differential Reinforcement of Other behavior (DRO), Differential Reinforcement of Low Rates (DRL). Differential reinforcement of incompatible behavior (DRI) is a procedure in which the teacher would identify a behavior that’s incompatible with, or cannot occur at the same time as, the problem behavior. Some studies found a much smaller treatment effect when the intervention simply reinforced a behavior that was topographically incompatible with the target behavior. DRI One way to get rid of a problem behavior, especially a dangerous behavior like self-injurious behavior (hitting one's self, biting one's self) is to reinforce a behavior that is incompatible: in other words, you can't hit yourself if you are doing something … She decides to reinforce a behavior that is incompatible with out of seat behavior. DRA: Differential Reinforcement of Alternate Behavior. For self-injurious or dangerous behaviors, there are significant ethical questions raised by withdrawing treatment. Differential reinforcement is defined as reinforcing a specific class of behavior while withholding reinforcement for other classes of behavior. This is Differential Reinforcement of an Alternate Behavior, (DRA), which serves the same function, providing him a sensory outlet for his hands during times of excitement of anxiety. Sitting in his seat is chosen as the incompatible behavior because it cannot occur at the same time as out of seat behavior. For more details, see our Privacy Policy. Another example of a DRI strategy could be throwing a ball for the client to catch every time they start to hit someone. DRI similar to dra in that it teasches a behavior that is functionally equivlane to the problem behavior. Differential Reinforcement of Incompatible Behavior (DRI) In this intervention, the reinforcer is given when another behavior is used or observed. This intervention differs from DRA because the new behavior is incompatible with the inappropriate behavior.
